- 6 Claims. (01. too-.232)

Thisinvention relates to improvementsin lock.-

ing devices to serve as an anti-theft medium for an outboard motor.

An object of this invention is to provide a device which is adapted to attach to a part of a conventional boat, for example the transom thereof, which consists of a mounting plate having a wall extending therefrom and a cover plate which is hinged to the mounting plate, there being special provision between the wall and the cover plate to accommodate a lock so that the 'cover maybe held substantially fixed with respect to-themounting plate and the wall, whereby when a locking rod or bolt is passed through an opening in the wall. and has a wing nut thereon, the wing nut may be held in a slot in the cover and the bolt arranged for sliding movement through the opening in the wall. By this expedient, a hook or-a number of hooks attached to the rod or bolt are capable of beingattached to a part ofthe motor clamp so that itois impossible to remove the motor clamp from the boat unless the anti-theft device is broken or opened.

apart of ;a boat; and

. Figure 4 'is an'elevational view of a slightly :modified formof the invention, the modification being that the device is slightly smaller in size andoslightly different in shape and has only one looking hook whereas the other form of the invention is provided with more than one locking hook.

Reference is first made to ,the embodiment of the invention shown in Figures 1-3. Here a boat l fragmentarily shown is provided with ,the usual parts, the transom l2 being most pertinent, although the device may be attached'to any part of the boat. The most practical use of the invention is on the transom inasmuch as the outboard motor [4 is generally held by means of a conventional clamp 16 .to the transom of a boat.

Substantially all conventional outboard motor clamps are provided with at least one and usually two clamp screws [8 which have a windingmember 20 at one end and which are adapted to opening :56 in the cover plate .42.

press against the transom I2 of a boat at the other end, usually through the medium of .a

pad 22 ofone .type or another. The docking or antietheft device is adapted to iasten to. the

(clamping screw orscrews 18 in orderito prevent their separation from the transom ;l;2 oi the boat 1.0.

Asdisclosed'in Figure 3 there is a rnounting plate 24 having alnumber of holes thereinthrough which the screws 26 pass so that they maybe anchored in the "WOQd of 'the transom 12. A wall 28, preferably integral with one ,edge .of the mounting plate 124',extends at right angles .from the mounting plate 24. This wall has an opening ;3O t;herein ,through whichithe .l or

bolt .32 passes. "This rod is capable of sliding movement through the opening {Di-and hasan eye '36 at .one'end (thereof. "The other enrl for the rod or "bolt 32 is threaded as at L38fa'nd is adapted to pass through apart of the slot which is formed in the cover p1at e 42. Theslot 40 is formedloi two parts 43 and 44, the part :43 being materi ally wider than the ipart'ifl (Figure 2).

The cover plate-.42 is hinged by means of .the

hinge 46 at its lower edgeto the lowerledgebf the mounting plate 24, whereby the coverplate is capable-of hinged or pivoted movement a out the hinge pin asan axis. Sides-48. and:-.5,0. .extend fromthe edges ;of the coveriplate 42, form n'g' a part thereof andc1osethe lateral .ends ,of thedevice.

-Means is "arranged at the upper edge of the cover plate lz and-theouter edge of the w l 1 2}! to accommodatethe-lock.52. This mea nsists of a tongue-54which passes {throng an ,o .A la ra e d ng fl n -5 is pr i a th top Etd of the cover plate ,42. Accordingly, when'the cover plate 42 is hingedly moved". the tongue 54 passes through the opening..55 so thatflthe lock 52 may-pass throughaligned openings in }the vflange .i-8;and the tonguefl54, thereby preventing any substantial movement of the cover p te with respect to the wall 28' or the mountingplate 24. In order ,to prevent separation of, th Jl'ock Q54;frorn-the device, a' chain so or othersuitable flexible element is attachedto the'loclrland a wall of the cover plate, for, example, the, ivail The bolt 32 has a locking..e1ement,'..for...example, the wing nut 64 on the threads 38 and is adapted to bear against the inside surface of the wall 28 or against a washer 66 when a washer is employed. Therefore, when the nut 64 is rotated in one direction the rod 32 is pulled inwardly through the opening 30. A part of the wing nut is adapted to be disposed in the reduced part 44 of the slot 40, when the cover 42 is hinged to the closed position to accommodate the lock 52. Through this expedient the nut 64 cannot be rotated and, therefore, the rod 32 cannot be moved. j g i A plurality of hooks 68 and iii are secured by means ofeyes to the eye 35 of the bolt or rod 32 and are adapted to lock on the clamping screws [8. Through this action the outboard motor clamp H3 cannot be separated from the transom IQ of the boat unles the lock 52 is removed and the device disassembled. Resilient means opposing the sliding movement of the .rod or bolt 32 in one direction is provided. This means consists of a spring 12 which reacts upon a collar 74 which is fixed to the rod 32. The spring also reacts upon a washer l6 which is simply disposed on the outer surface of the wall 28. Therefore, when the nut 64 is tightened the rod 32 is pulled downwardly to firmly clamp the hooks 68 andll) on the clamp screws I6 against the opposing forceof the spring 12. Reference is now made to Figure 4 wherein the second embodiment of the invention is disclosed; The internal structure, make-up and operation of the embodiment of Figure 4 is identical to that previously described. The outside wall 80 which would normally correspond to the wall or side 5B is of slightly diiferent shape. 'The'device' isarranged in this fashion so that it-may be more properly-and easily usedin connection with the transom 8 2 of a boat which has a'brace 8 5. rising at the center thereof. This is simply "another type of conventional boat and the locking device 88 is adapted specifically for this type of transom. In lieu of the pair of hooks 68 and 10, only one hook 88 is used at the end of the bolt 90. This is the case inasmuch as it is contemplated to use two identical locking devices 86 and 92 in instances wherein there is adivided transom. Therefore, only one hook 823 is necessary.

Having described the invention, what is claimed as new is:

1, For use with an outboard motor'clamp, an anti-theft device comprising a. mounting plate adapted. to be fixed to a part of a boat, a wall having an opening therein and extending from said mounting plate, a cover plate hinged to said ,mounting plate and having a slot, means connected with said wall and said cover plate to accommodate a lock for holding said cover plate substantially fixed with respect to said cover plate, a rod slidably disposed in said opening and having a locking element disposed thereon and .partialy disposed in said slot, and means secured to said rod for fastening said rod to a part of the 'mountingplate and having a slot, means connected with said wall and said cover plate to accommodate a lock for holding said cover plate substantially fixed with respect to said cover plate,
